Any additional steps besides your blog post?
I will most probably not use Fedora but used F15 and F16 for some
time. That shouldn't be a problem, but I had hoped mjg's EFI work
in Fedora to produce a smooth setup experience which F17 Alpha
didn't yet deliver as far as my experiments went. He's doing hard work
and it will sure pay off.

Maintaining a grub2 cfg file without Debian's or Fedora's generator
(or is it grub2-mkconfig now in grub2?) is actually simple.
Excluding kernel version strings the config should be fairly static.
BTW, do you know the status of the EFI boot stub patches in 3.2 and 3.3?
That sounded useful to directly boot a kernel image as an EFI application.
Fedora's grub2 scripts always messed up the saved boot target
everytime a new kernel was installed. I'd guess some part of it
overwrites the meta file.
